... 1. The Zope-2.7.0\doc\INSTALL.TXT describes installing Zope from source. If I follow this description, what will then happen to the Zope 2.6.2 that I am allready running?
Nothing, unless you choose to put the new Zope in the old place. Do not do that (until everything works to your needs).
2. Should I do something with my Zope 2.6.2 before starting installing Zope 2.7.0?
This is not necessary. When your new Zope should use the same ports as your old one, you must shutdown the old one before you can start the new one. But for testing, just let the new one use different ports.
3. After following the above installation guide. Can I then just take the data.fs file from Zope 2.6.2 and put it into the \Zope-Instance\var\ directory of my new Zope-2.7.0, restart Zope, and then be happy running the "old" web applications again?
Yes, at least ideally. There might be some problems (such as missing products).
4. Or can I/should I just export my Zope 2.6.2 web applications and then import them into Zope-2.7.0?
No, unless you want only to move part of your Zope site. Even then copying and deleting is usally better... -- Dieter
